Abstract

Melting fuse with a melting wire arranged between a first and a second terminal, characterized in that a connecting pin is arranged on each of the first and second terminals, a printed circuit board is placed on the connection pin, and at least one integrated circuit is arranged on the printed circuit board on the side facing away from the melting wire.

First claim

What is claimed is:

1. Melting fuse comprising:
a melting wire arranged between a first and a second terminal;
a connection pin arranged on each of the first and second terminals;
a printed circuit board placed on the connection pins; and
at least one integrated circuit arranged on the printed circuit board on the side facing away from the melting wire, wherein
the at least one integrated circuit comprises at least one microcontroller, and
the at least one integrated circuit is electrically powered via the connection pins, wherein the integrated circuit is operated by a voltage drop across the melting wire.

2. Melting fuse according to claim 1 , wherein the printed circuit board is placed on the connection pins with vias.

3. Melting fuse according to claim 1 , wherein an insulation layer is arranged between the melting wire and the printed circuit board.

4. Melting fuse according to claim 1 , wherein the connection pins and the melting wire are arranged in a U-shape with respect to each other.

5. Melting fuse according to claim 1 , wherein the first and second terminals extend along a longitudinal axis, the longitudinal axes of the terminals are substantially parallel to each other, the melting wire is substantially perpendicular to the longitudinal axes of the terminals, and the connection pins are substantially parallel to the respective longitudinal axes of the respective terminals.

6. Melting fuse according to claim 1 , wherein the terminals are formed as flat tabs and the connection pins are formed in the shape of wires.

7. Melting fuse according to claim 1 , wherein the respective terminals and connection pins are formed in one piece.

8. Melting fuse according to claim 1 , wherein the terminals and the melting wire are arranged on a substrate, the connection pins protrude from the substrate, and the printed circuit board is separated from the substrate.

9. Melting fuse according to claim 1 , wherein the terminals and the melting wire are arranged in a common housing, in particular encapsulated, and the connection pins are guided out of the housing.

10. Melting fuse according to claim 1 , wherein a voltage and/or a current via the melting wire and/or a temperature at the melting wire can be tapped on the printed circuit board via the connection pins.

11. Circuit arrangement including a melting fuse according to claim 1 , a battery and at least one load, the battery being electrically connected to the melting fuse via the first terminal, and the load being connected to the melting fuse via the second terminal.

12. Motor vehicle comprising a circuit arrangement according to claim 11 .
